BUNDLE COMPRESSOR AND EJECTOR FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 259,897, dated June 20,1882.

- Application filed December 27, 1881. (N0 model.) 7

To all whom it may concern Be it known that I, LEwIs MILLER, of Akron,in the county of Summit and State of Ohio, have invented certain new anduseful Improvements in Bundle Compressors and Ejectors forGrain-Binders; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, in whichFigure 1 is a side elevation, showing the position of the parts as thebinding-arm descends; Fig. 2, a similar view, showing the position ofthe parts at the moment the bundle is ejected.

Similar letters of reference in the several figures denote the sameparts.

This invention relates to an improved bundle compressor and ejector forharvester-bind ers, arranged and adapted to operate substantially as Iwill now proceed to describe.

Referring to the drawings, A represents a binding-arm; B, a crank havinga wrist, 1), upon which the binding-arm is mounted so as to turn freely;O, a rotating shaft to which the crank is secured; D, a bracket or framehaving a horizontal arm which overhangs the binding-table E and supportsthe shaft 0; and G is a slotted guide adapted to guide and control theheel of the binding-arm. All these parts are arranged in the properrelation to each other, and are adapted to operate in the usual manner.V

Mounted at it upon the binding-arm, near the point where said arm ishung upon the crank-wrist and so as to turn easily, is acoinpressing-arm, H, the same having a point, h,

heel 71. and a short arm, W, by which it is connected to thebinding-arm. A flexible compressing cord or Wire, [L4, extends from nearthe extremity of the point h through an eye or over a pulley at the endof the heel 71. and is attached to a spiral spring, h connectedto ahook, if, as shown. A spiral spring, a, is connected at one end to theshort arm h of the compressor, and at the other end to a hook, or, uponthe binding-arm, nearthe end of its heel, as shown. The crank-wrist bprojects some distance through the binding-arm and upon its end isfirmly secured a short curved arm or cam, K.

When the point of the binding-arm is elevated and while it is descendingto separate a bundle of grain the cam K stands up as shown in Fig. I,and the tension of the spring a 5 causes the point of the compressor-armto lie close against the binding-arm, preferably up against a flange, aformed on the bindingarm. As the binding-arm descends the flexible cordh of the compressor comes down upon the gathered bundle, and as thebindingarm passes-toward the front edge of the table the cam K strikes ashoulder, h on the compressor-arm, and, overcoming the tension of thespring a, forces the point of the compressor away from the binding-arm,and thereby causes the compressor to advance in front of thebinding-arm, increases the pressure of the flexible compressing-cord htupon the bundle, and finally sweeps the bundle from the table. When thebinding-arm again begins to rise, the cam becomes disengaged from theshoulder h of the compressor-arm, and a curved portion, 71 on thecompressor, comes gradually in contact with its curved back until thecompressor is brought back to its first position,.as shown in Fig. 1. v

I do not desire to be limited to the precise embodiment of my inventionhere shown, as other embodiments containing the essential features of itcan be devised by any skillful mechanic.

What I claim as new is- 1. The combination, substantially as described,of a rotating crank, a binding-arm mounted upon the wrist of said crank,means for controlling the movement of the bindingarm, a compressorsupported wholly by the binding-arm and moving therewith, and an armsecured rigidly to the crank-wrist and adapted to strike the' compressorand positively move it in advance of the binding-arm to eject thebundle.

2. The combination of the binding-arm, the compressor mounted upon andmoving with the binding-arm and having the shoulder, the springconnected at one end to the binding arm and at the other to thecompressor, and

the curved arm or com on the crank-Wrist, the compressing-arm, and thecurved arm seoperating in connection with the shoulder on cured rigidlyto the crank and operating in the compressor, substantially asdescribed. connection with the shoulder h and the curved 3. Thecombination, with the crank, of the portion h of the compressing-arm, asset forth. binding-arm mounted thereon, the compress- LEWIS MILLER.ing-arm supported by the binding-arm and having the shoulder h andcurved portion h, the spring connecting the binding-arm with Witnesses:
